2.1.1.6 Function Description

Bluetooth
and up to seven slaves. Data can be exchanged between each slave and the
master wirelessly and bidirectionally. Data transfer from slave to slave is pos-
sible indirectly through the master.
The Bluetooth
configured as either master or slave. The configuration and activation of spe-
cial functions is done through the mailbox interface described in Appendix
6.1. This is used by the startup tool WAGO-I/O-CHECK and function blocks
of WAGO-I/O-PRO CAA in order to provide the user with simple software-
supported access to the module's full range of functions.
The following networks can be configured with Bluetooth

width for bidirectional data exchange with the slaves. In this case, which proc-
ess data is assigned to which slave can be flexibly configured – the available
data width can be assigned exclusively to one individual slave or be distrib-
uted with freely configurable portions among several slaves.

visibility. Good reception is also possible inside buildings, even with the dis-
tribution of network participants in different rooms or floors of the building.
For maximum security, data exchange can be encrypted. Another security fea-
ture of the network is that a piconet configured with Bluetooth
lows no penetration by non-authorized devices.

outside influences. Thanks to frequency hopping procedures and adaptive
transmitting power, co-existence with other ISM radio technologies (e.g.
WLAN according to IEEE 802.11) is problem-free.
Potential-disturbing influences can be recognized early by the Bluetooth
module – even before they have a negative effect on communication. Cyclic
and acyclic retrievable diagnostic information that provide information on the
quality of the wireless connection and fulfillment of real-time conditions (in
